New Hardware Feature Support
Cisco 860 Series Integrated Services Routers
Cisco IOS Software Release 15.2(2)T supports r the Cisco 860VAE Integrated Services Router, Generation 2. The
Cisco 860VAE is ideal for deployments into small offices or service provider managed CPEs. The Cisco 860VAE
is flexible, silent, compact and cost optimized. The Cisco 860VAE provides multiple WAN options for maximum
deployment flexibility, along with optional market leading features such as Scansafe connector, BGP, IPSec and
firewall. The Cisco 860VAE series ISR is available as a Base Router (BR) with an IPBase IOS image, or as a
Secure Router (SR) with an advanced security IOS image, with or without payload encryption.
G.SHDSL EFM/ATM Multimode
The Cisco multimode 4-pair G.SHDSL enhanced high speed WAN interface card is designed to deliver high-speed
Ethernet services over SHDSL access, as required in Ethernet in the first mile (EFM)/Asynchronous Transfer
Mode (ATM) service networks. EHWIC-4SHDSL-EA will offer symmetric data rates over one to four pairs (1-4) of
copper wire, and supports both EFM and ATM modes. They connect Cisco Integrated Services Routers
Generation 2 (ISR G2s) with central office digital subscriber line access multiplexers (DSLAMs), and provide up to
four lines of G.SHDSL (ITU-T 991.2) connectivity. The C888EA provides four pairs of multimode G.SHDSL
connectivity.

Security
Cisco TrustSec Solution on ISR Platforms
Cisco TrustSec Solution (CTS) is a system that provides security for CTS-enabled network devices at each routing
hop. In this system, each network device works to authenticate and authorize its neighbor devices and applies
some level of security (group tagging, role-based Access Control Lists (ACLs), encryption, etc.) to traffic between
the devices.
The Cisco TrustSec network policy based access control runs on the Cisco Integrated Services Routers
Generation 2 (ISR G2) providing policy based access uniquely positioned for the branch office. Cisco TrustSec
provides policy based access and user identity context awareness that is secure and scalable, all with simplified
ease of deployment. In addition, this feature enables business productivity, delivers security and risk
management, as well as improves IT operational efficiency.
Cisco TrustSec delivers consistent identity features supported on ISR G2 switch models, in addition to
authenticating authorized users (802.1X), devices (MAB/profiling) and guests (Web Auth).
FlexVPN Spoke-To-Spoke
FlexVPN Spoke to Spoke allows a FlexVPN client to create a direct flex tunnel with another FlexVPN client by
leveraging the Virtual Tunnel Interfaces (VTI), Internet Key Exchange Version 2 (IKEv2) and Next Hop Resolution
Protocol (NHRP) in building a Spoke-to-Spoke connected relationship.
The Internet Key Exchange Version (IKEv2) is a next-generation key management protocol based on RFC 4306
as an enhancement of the original IKE Protocol. IKEv2 is used for performing mutual authentication and
establishing and maintaining Security Associations (SAs).
FlexVPN is the Cisco implementation of the IKEv2 standard that features a unified paradigm and CLI, that also
brings together four VPN topologies; site to site, remote access, partial mesh (spoke to spoke direct), and hub to
spoke designs. FlexVPN's simple but modular framework extensively leverages the tunnel interface archetype
while remaining compatible with traditional VPN's through the use of crypto maps.
DMVPN NHRP Event Publisher
The DMVPN Next Hop Resolution Protocol (NHRP) event publisher allows you to publish NHRP specific events to
its Event Detector (ED), so they can be intercepted and acted upon by the Embedded Event Manager (EEM)
system through the use of custom scripts. In this system, NHRP publishes its own NHRP specific events with data
to the NHRP-ED handler. The DMVPN NHRP event publisher feature enhances Dynamic Multipoint VPN
(DMVPN) with the capability to monitor, control, and react to the building of dynamic spoke-to-spoke tunnels in
real-time through NHRP. The EEM combined with NHRP can leverage the actions of the NHRP-ED to support
unique deployment requirements, when building dynamic spoke-to-spoke tunnels.
Routing Innovations
LISP Network Virtualization
LISP is a network architecture and protocol that implements a new semantic for IP addressing, by creating two
new namespaces: Endpoint Identifiers (EIDs), which are assigned to end hosts, and Routing Locators (RLOCs),
which are assigned to devices (primarily routers) that make up the global routing system. Splitting EID and RLOC

functions yields several advantages including improved routing system scalability, improved multi-homing
efficiency and ingress traffic engineering. LISP support is configured on devices such as Cisco routers.
To provide improved routing scalability while also facilitating flexible address assignment for multi-homing,
provider independence, mobility and virtualization, the Locator Identifier Separation Protocol (LISP) was created.
LISP describes a change to the Internet architecture in which separate IP addresses are used to indicate RLOCs
for routing through the global Internet, and EIDs for identifying network sessions between devices.
OSPFv3 Not-So-Stubby Area (NSSA) Option—RFC 3101
In OSPF for IPv4, stub and NSSA areas were designed to minimize link-state database and routing table sizes for
the areas' internal routers. This allows routers with minimal resources to participate in even very large OSPF
routing domains.
In OSPF for IPv6, the concept of stub and NSSA areas are retained. In IPv6, of the mandatory LSA types, stub
areas carry only router-LSAs, network-LSAs, inter-area-prefix-LSAs, link-LSAs, and intra-area-prefix-LSAs. NSSA
areas are restricted to these types and NSSA-LSAs. This is the IPv6 equivalent of the LSA types carried in IPv4
stub areas: router-LSAs, network-LSAs, type 3 summary-LSAs and for NSSA areas: stub area types and NSSALSAs.
Cloud and Virtualization
Next Generation Network Based Application Recognition (NBAR)
NBAR Categorization and Attributes
The NBAR categorization and attributes feature provides the mechanism of matching the protocols grouped under
specific categories based on the attributes. These categories are available for Class-Based Policy Language
(CPL) as a match criteria for application recognition.
Because there are many protocols and applications, categorizing them into different groups will help with reporting
as well as performing group actions, such as applying QoS policies, on them. Attributes are statically assigned to
each protocol or application, and they are not dependent on the traffic. The following attributes are available to
configure the match criteria using the match protocol attribute command. They are the Application-Group,
Category, Sub-Category, Encrypted, and Tunnel attributes.
NBAR PDL Support in Release 15.2(2)T
NBAR PDL adds support for 30 new protocols in release 15.2(2)T, adding to the already extensive PDL support on
the ISR platforms. In the previous 15.2(1)T release, 38 additional new protocols were added to a growing list that
now contains over 1,000 unique protocols.
Visit: http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6558/ps6616/product_bulletin_c25627831.html to see the list of the NBAR protocols available.
NBAR Protocol Pack
The NBAR protocol pack feature provides an easy way to load a protocol pack, which is essentially a single
compressed file that contains multiple Protocol Description Language (PDL) files and a manifest file for them all as
one. Using NBAR protocol packs, a set of required protocols can be loaded in a more simplified manner, in a

single operation, making rapid changes one less thing to be concerned about. This helps Network-Based
Application Recognition (NBAR) recognize additional protocols for classification on your network.
NBAR Protocol Pack Overview
Application recognition modules (also known as PDLMs) can be used to extend the functionality of NBAR, by
enabling NBAR to recognize additional protocols on your network. A PDLM is used to add support for a protocol
that is currently not available as part of the Cisco IOS Software. A PDLM extends the list of protocols that NBAR
can recognize.
A protocol pack is a single compressed file that contains multiple PDL files and a manifest file. Your company or
organization determines the contents of the protocol pack. Protocol packs allow you to load a set of protocols
together versus loading them separately.
NBAR protocol packs provide three benefits:
1.
They help to simplify the loading of new protocols.
2.
They make it easier to upgrade to a higher version protocol pack or revert to a lower version protocol pack .
3.
They provide only the required set of protocols.
Cisco provides a specific identity number for the organization (also known as the "publisher") that creates the
protocol packs and uses Cisco tools and processes to create new protocol packs. The organization that creates
the protocol pack owns the pack. The Default Protocol Pack (DPP) is provided as the base protocol pack version
with the Cisco IOS image in the router.
Performance Routing (PfR) Data Export 1.0
The Performance Routing (PfR) Data Export v1.0 NetFlow v9 Format feature allows your NMS systems to simplify
real-time data collection from PfR. The data is exported in real-time over the NetFlow v9 transport supported in
RFC 3954. PfR exports both regular performance trend data, as well as PfR Route Policy Control Events, or realtime Out Of Policy Alerts and their data.
This feature exports data from the Master Controller (MC) to data collectors in your network and allows you to see
more easily how your critical business applications and networks are performing, in addition to letting you know
the moment PfR takes any protective actions based on your company set policies, to instantly redirect your critical
business applications onto a safe and stable path, letting you know Performance Routing is helping keep your
business running.
Performance Routing (PfR) Data Export in NetFlow v9 (RFC 3954) allows you to simplify real-time application and
network performance PfR policy change notifications, trends, and correlations. This is based on the NetFlow v9
standard protocol and formats under RFC 3954. This feature exports both regular time-based performance data,
as well as PfR Route Policy Control Events based data.
Video and Collaboration
IP Service Level Agreements (IP SLAs) Video Operation
IP Service Level Agreements (SLAs) is a feature embedded in Cisco software. This feature allows you to
understand IP service levels, increase productivity, lower operational costs, and reduce the frequency of network

outages. IP SLAs perform the active monitoring of network performance and can be used for network
troubleshooting, network readiness assessment and health monitoring.
The Cisco IP SLAs Video Operation feature generates synthetic traffic and creates a custom profile from that
activity. This feature can imitate a sufficient packet generation for a true video stream. IP SLAs Video Operation
capable devices can act as a source or a responder for their video operations.
Video Monitoring MIB Support for Medianet Video Monitoring
This feature provides support for the use of the industry-standard Simple Network Management Protocol (SNMP)
to monitor media streams. This support is implemented with the addition of the following Cisco specific SNMP
Management Information Base (MIB) modules:
●
CISCO-FLOW-MONITOR-TC-MIB—Defines the textual conventions common to the following MIB modules.
●
CISCO-FLOW-MONITOR-MIB—Defines the framework that describes the flow monitors supported by a
system, the flows that it has learned, and the flow metrics collected for those flows.
●
CISCO-MDI-METRICS-MIB—Defines objects that describe the quality metrics collected for media streams
that comply to the Media Delivery Index (MDI) [RFC 4445].
●
CISCO-RTP-METRICS-MIB—Defines objects that describe the quality metrics collected for RTP streams,
similar to those described by an RTCP Receiver Report packet [RFC 3550].
●
CISCO-IP-CBR-METRICS-MIB—Defines objects that describe the quality metrics collected for IP streams
that have a Constant Bit Rate (CBR).
Performance Monitor (Phase 2)
Cisco Performance Monitor Phase 2 introduces IPv6 support, which enables configuration of IPv6 fields, and this
release also introduces Flex Keys support which opens up all the remaining Flexible NetFlow collect and match
commands for use that were not supported in the previous release. Cisco Performance Monitor Phase 2 continues
to enable monitoring of the flow of packets in your network and it will become aware of any issues that might
impact the flow, before it starts to significantly impact the performance of the application in question. Performance
monitoring is especially important for video traffic because high quality interactive video traffic is highly sensitive to
network issues. Even minor issues that may not affect other applications, may have dramatic effects on video
quality.
New in this release is where flows are now correlated, if the same policy is applied on the same input and output
interface, the show command will display a single flow for the input and output interfaces.
Cisco Performance Monitor uses similar software components and commands as Cisco NetFlow and Cisco
Flexible NetFlow, familiarity with these products will help you to understand how to configure Cisco Performance
Monitor. These products provide statistics on packets flowing through a router and are the standard for acquiring
IP operational data from IP networks.
NAT Aware RSVP
RSVP technology is used for three primary purposes today: RSVP CAC, RSVP as Transport, and RSVP-TE.
Commonly, in the first two applications of the three (RSVP CAC and RSVP as Transport), the RSVP control plane
messages need to transit through and be processed by the Network Address Translator (NAT) devices. NATs,
while providing many benefits and being very common today, also comes with occasional challenges in some

Page 6 of 10
network designs. One of these challenges is the fact that they interfere with some existing IP applications, and it
can be difficult to deploy new applications.
RSVP, like many other control plane protocols (SIP, ICMP, etc.), have embedded IP addresses as part of their
control plane messages. These IP addresses are used for path determination as well, and since RSVP messages
are not handled by NAT devices today, RSVP applications work incorrectly in a NAT network deployment based
scenario.
NAT Aware RSVP enables RSVP-Network Address Translation (NAT)-Application Layer Gateway (ALG)
functionality. Now the RSVP-NAT-ALG functionality is enabled, and as the RSVP messages pass through a NAT
device, the IP addresses embedded in the RSVP payload get translated appropriately.
Network Management
Embedded Event Manager (EEM) Version 4.0
EEM Version 4.0 features major enhancements on security, resource throttling, deployment, performance, and
usability.
®
Cisco IOS Embedded Event Manager (EEM) is a unique capability in Cisco IOS Software. EEM is a powerful and
flexible tool used to automate tasks and customize the behavior of other Cisco IOS Software features and
capabilities to suit the operations of the device to your needs. Customers use EEM to create and run programs or
scripts directly on their router or switch. The scripts are referred to as EEM policies and can be programmed using
a simple Command-Line-Interface (CLI)-based interface or using a complete scripting language called Tool
Command Language (Tcl). EEM allows customers to harness the significant intelligence within Cisco IOS
Software to respond to real-time events, automate tasks, create customized commands, and take local automated
action based on conditions detected by the Cisco IOS Software itself.
Below is a short list of v4.0 features and benefits. In this release, the following enhancements related to EEM
security, resource management, event detection and policy execution capabilities are introduced:
●
EEM Email Action Enhancements
◦
Custom TCP port for SMTP mail actions
◦
Tcl-based and CLI-based EEM policies to establish secured SMTP connections with public email servers
using Transport Layer Security (TLS)
●
●
●
EEM Security Enhancements
◦

length of policy execution time, and next policy execution for timed events
◦
Powerful file operation support for applet policies
IPv6 Compliance of Cisco IPSec MIBs and IKEv2 Extensions to Cisco IPSec MIB
The IPv6 compliance of Cisco IPSec MIBs and IKEv2 extensions to Cisco IPSec MIB feature provides IPv6 and
IKEv2 support for the Cisco IPSec MIBs.
The following MIBs are supported by the IPSec and IKE MIB support for Cisco VRF-Aware IPSec feature:
●
CISCO-IPSEC-FLOW-MONITOR-MIB
●
CISCO-IPSEC-MIB
The CISCO-IPSEC-POLICY-MAP-MIB continues to be supported. However, because this MIB applies to the entire
router rather than to a specific VPN VRF instance, it is not VRF aware; therefore, polling of the Object Identifiers
(OIDs) that belong to this MIB is accomplished with respect to the global VRF context.
Flexible NetFlow: Export to an IPv6 Address
This feature enables Flexible NetFlow to export data to a destination using an IPv6 address. A flow exporter allows
Flexible NetFlow to export data from the network device to remote NMS collector systems, such as a UNIX server
running a NetFlow collector server. Now the NetFlow collector's destination address can be an IPv6 host network
address or an IPv4 address.
Irrespective of whether or not the data being exported carries IPv6, IPv4, or a combination of both types of network
traffic information, customers can now send that information onto any v4 or v6 NetFlow collector necessary. This is
another step to help simplify your company preparation and migration to IPv6 as Flexible NetFlow is one of the
most widely used Cisco IOS measurement technologies today.
NetFlow provides statistics on packets flowing through the router. NetFlow is the standard for acquiring IP
operational data from IP networks, and provides data to support network and security monitoring, network
planning, traffic analysis, and IP accounting.
